and I get the errors below as result

 Error using PMImport.ModelReader
"Join_2new_v6.xml" not found. Could not import the
specified XML file.

Error in PMImport.ModelUpdater

Error in PMImport.pmiu_import

Error in mech_import (line 98)
    PMImport.pmiu_import(varargin{:});   

what does the errors mean? what should I do for the model appear in simMechanics/simscape?

The error says....MATLAB is unable to find the said file. See to it that the file given is in the present working direcotry or the path of the file is given correct.

As KSSV noted, the error message "... not found" means the file is not in the current working directory and it is not on the path. You can get past that error by moving to the directory where the file is located and running the command again.
